field of view in the context of video games is the total angular extent of any
0:05
scene that can be viewed on the screen at any given moment got that great
0:09
thanks for watching give us a like or dislike share comments okay maybe I
0:12
should explain it a bit better than that now your own eyes assuming you're a
0:16
human can see almost 180° of the world
0:19
out in front of you but a monitor huge enough to take up your entire field of
0:23
vision would be really really impractical for a variety of obvious
0:28
reasons so if you're sitting a norm distance away from a reasonably sized
0:32
screen it will take up something like 30 or 40 horizontal degrees of your vision
0:39
but if the camera within a first-person video game is set up to show only 40° of
0:44
the game World well that's a bit of a problem you've got no peripheral vision
0:49
some first-person video games that I've played certainly do suffer from this
0:52
tunnel vision effect which is pretty terrible when there are people shooting
0:56
at you that you can't even see also a
0:59
narrower field of view causes many gamers to feel nauseated while playing
1:03
because camera movements are more exaggerated all right so here's the
1:07
other extreme now we're on a GoPro Hero 3 plus which has something like a 170°
1:12
horizontal field of view so even if the screen you're watching this on takes up
1:16
only 40° of your vision you can still see
1:21
170° in this scene here this definitely
1:24
solves the tunnel vision problem but it's not a perfect solution first of all
1:29
everything on screen is now smaller and therefore more difficult to see secondly
1:33
with extremely wide angle views you get this funny sort of distortion that
1:37
occurs around the edges of the scene so how do Gamers solve this problem one way
1:42
is to add more screens but then of course you have to go buy more screens
1:46
and maybe a monitor stand and then maybe a better graphics card to help you
1:50
render out all those pixels but that's an expensive way to go another option is
1:55
to change the field of view or fov slider within the game to whatever is
2:00
most comfortable for you however some games don't have this option so why
2:05
would a game developer leave that out well one reason is the dreaded CPS or
2:10
console Port syndrome for a console game you're usually going to be sitting
2:14
farther away from the screen so a narrower field of view looks and feels
2:19
more natural even if it does result in tunnel vision it also requires less
2:23
processing power widening the field of view puts more objects on screen which
2:28
makes the game more demanding for little console to render so console games are
2:32
often made without a field of view slider to optimize performance and so
2:36
the ported PC version sometimes doesn't get one either and that's a real shame
2:41
you know what else is a real shame my lack of beard in this episode You see
2:46
I've received a number of really lovely comments telling me to shave my beard
2:49
